Covariant perturbations through a simple non-singular bounce
Atanu Kumar
In this paper we study the evolution of cosmological perturbations through a nonsingular bouncing universe using covariant perturbation theory and examine the validity of linear pe…

Growth of covariant perturbations in the contracting phase of a bouncing universe
Atanu Kumar
In this paper we examine the validity of the linear perturbation theory near a bounce in the covariant analysis. Some linearity parameters are defined to set up conditions for a li…
